sobre una superficie sin fricción de un objeto de 10kg en movimiento choca con un objeto de 5 kg en reposo. Si los objetos quedan pegados durante el choque con una rapidez de 4 m/s. ¿Cuál es el valor de la velocidad inicial del objeto en movimiento antes del choque?

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the force on the thing and the distance the force moves the thing

neither accurate nor precise.
